Specification of Letters Patent.

Application filed October 31, 1911.

Patented ,Mar. 19, 1912. Serial No. 657,737.

To all whom it may concern Be it known that I, Mnr'rnms CHRISTMAN,

a citizen of the United States, residing at Springfield, in the countyof Greene and State of Missouri, have invented certain new and" usefulImprovements in l/Vheel-l'lub Plates, of which the following is aspecification, reference being had therein to the accompanying drawing.

This invention relates to hub plates, and the principal object of thesame is to provide the hub plate with liner bands which Wlll hold thesections of the hub plate together and which will also hold the hubplate in the hub of the wheel.

This invention is illustrated in the accompanying drawings, whereinFigure 1' is a perspective view of the improved hub plate. Fig. 2 1s aperspective view of one of the sections of the hub plate. Fig. 3 is aview of one of the outer liners which surround the hub plate and holdthe sections together. Fig. 4-is a view of one of the inner linerswhichis positioned within the hub plates and which assists in holdingthe sections togethen Fig. 5 is a fragmentary View of the hub of thewheel showing the improved hub plate in place.

This hub plate is intended to be used on the driving wheel of alocomotive and is seated within an annular recess 1, which is formedinthe inner face of the Wheel 2 and is spaced from the central opening 3of the wheel by an annular shoulder 4;.

The hub plate comprises a pair of sections 5 and 6 each of which issemi'circular. The plates of the sections .are held together by means ofthe tenons 7 which are formed upon the nds of the section 5 andfitwithin the mortises 8 which are cut in the ends of the section 6. Theinner portion of each of the sections is reduced and is provided withthe internal groove\9 anclwvith the external groove 10. By having theinner portion of the section reduced the ledges 11 and 12 are formedupon which the locking liners rest.

The locking liners comprise the inner semi-circular bands 1' each ofwhich is provided with the flange 14: which extends into the groove 9.The l puter liners are also formed from semi-cirbular hands 15 each ofwhich is provided with the flange 16 which fits Within the grooves 10.The inner liner is of such dimension that it will fit snugly within thegrooves 9, and notproject beyond the flange 11. The outer liners 1.5 areformed from spring metal and are slightly sprung so that the endportions project slightly beyond the flange 12 so that when the plate ispositioned within the recess 1 the outer liners will be slightlycompressed and cause the plate to be held within the recess by thespring action of the outer liners.

The inner face of the plate provided with the annular groove 17, and aplurality of openings 18 lead from the groove 17 through the plate topermit the passage of securing pins 19 which enter sockets formed in thehub and prevent rotary movement of the plate in the wheel hub.

In the operation of the device the two sectlons of the hub plate areplaced together with the internal and external liner bands in positionas shown in Fig. 1. In order to insert the plate in the recess formed inthe hub the outer bands have to be compressed slightly. \Vhenthe plateis inthe recess the bands expand and frictionally engage the sides ofthe recess thus-holding the plate sections together and the plate in therecess.

What Iclaim as my invention is 1. A. wheel provided with an annularrecess, a hub plate mounted within said recess, said hub plate providedwith a reduced inner end and with annular grooves formed therein to formseats, locklng rings positioned within said seats to hold said platewithin said recess, and means for locking said plate against rotationwithin said recess.

2. A wheel provided with an annular reccss, a hub plate mounted withinsaid recess, saidhub plate formed ofa plurality of arcuate sect1ons,interlocking joints formed upon theabutting ends of said sections, theinner portions of said sections being provided with annular groovesforming seats, and locking bands mounted withln saidseats and adapted tosecure said sections together and hold said plate within said recess. v

3. A wheel provided with an annular recess, a hub plate'mounted withinsaid recess, said hub plate formed of a plurality of sections, commonmeans for holding said sections together, and for holding said hub platewithin said recess, and common means for preventing the rotation of saidplate within said recess and for permitting the passage of a lubricantthrough said plate.

A hub plate comprising sections provided with grooves tli inner seats toholdsaid plate in position.

6. A hub plate formed from a plurality of arcuate sections, interlockingjoints formed upon the abutting ends of said sections, said sectionsbeing provided with annular grooves forn'ling seats, locking bands mounted. Within said seats and adapted to secure said sections together andhold said platein position.

7. A hub plate formed from a plurality of sections, common 1116211192501holding said sections togetlier'and for holding said hub plate Within arecess, and means for preventing the rotation of said plate witliintherecess and for permitting the passage ofa lubricant through said plate.

8. A Wheel. provided with an annular recess, a hot: plate mountedwitiiinsaid are cess, said hub plate comprising arcuate seei I I ing formedfrom rigid metal and said. outer band being formed from resilient metal.

12. A. hub plate comprising a plurality of sections, bands positionedWithin said plate i In testimony whereof I hereunto aflix my signaturein presence of two Witnesses.
